- VirtualBox might no longer support
VBoxInternal/Devices/lsilogicsas/0/LUN#0/AttachedDriver/Config/ReadOnly
. Settings set thorughVBoxManage setextradata
are not officially supported and might be gone at some time such as now.- VirtualBox documentation chapter Special Image Write Modes mentions
immutable images
